ClassCastException: org.apache.struts.taglib.html.MessagesTei

Hi,

I have an old app which was developed under struts 1.2.8 using struts- 
tiles, and has undergone steady development.
However, /AS FAR AS  I KNOW/, no changes to the tags library files  
have been made for a long time.
Yet today, after rebuilding the project (using Project > Clean in  
Eclipse), I suddenly am getting this exception:

java.lang.ClassCastException: org.apache.struts.taglib.html.MessagesTei

(The full exception is shown at the end of this message)  I don't  
recall ever seeing this before, and am not sure what to do to solve  
the problem.

I'll greatly appreciate any suggestions anyone can offer.
Thanks in advance,
Ken Bowen
